Or the 4th thing, a plane is currently in-between the satellite and your home, falling at a high rate of speed. Might wanna go out for lunch!

That resolution is pretty amazing. I can even make out where the newer sidewalk section is directly in front of my house, where they had to do some gas line repairs a few years ago.

I'd guess from looking at it, that its better than the standard 1meter pixel res of largescale satelite pics, and the fact that its color does indicate its better than that..........I'd suspect its been done by your local govt(city/count) and provided to USGS. Its hard to tell, but I'll bet its 1' or 9" pixels, which allows you to zoom in and see stuff better at closer range.

A nice sidelight of having Lambert about 10 miles north and 5 west of my position, is that it is on an East/West footing. There is absolutely no reason for an airplane to be overhead. It'd have to purposefully take off and make a really hard turn to even get there. Tons of air traffic 10 miles north, though.

We do have a major USGS service center just adjacent to the Budweiser plant here in town. My aunt and uncle worked there a long time ago, and they gave me a huge color printout of the entire St. Louis Metro Area. East St. Louis to O'Fallon, Alton to Arnold. It was about 5' by 3'.

Looks like about 618 ft... and that's my house right below the red tack!

How are you guys posting the pictures? I want to put up a photo of my house, too.

PastorMikH 12-23-2004 10:57 AM

I'm curious as to how BabyLee got that pic in color.

Urban areas are in color, and non-urban areas are still in black and white. I've got full technicolor on my picture, too.

Ah. There we go. My house is the one with the dark roof just to the right of the pushpin. I think that handicapped guy is parked in the alley again.

In a bigger view, you can see that we're definitely in the city. (We're still at the red pushpin.) We've got an awesome park and botanic garden northeast of us, and the downtown area (where I work) is just barely out of the picture to the northwest. That slanty road on the southwest end of the picture runs along Cherry Creek, which is one of Denver's most grand waterways. (It's about 12 feet wide and 2 feet deep.)

Just north of us is an old turn of the century elementary school where Mamie Eisenhower attended as a child, and just north of that is our grocery store, just on the off chance that anyone really cares.

Those USGS photos are 10 years old.

I found my house and it doesn't even look the same, since it was remodeled completely in 1998.

Rain Man 12-23-2004 11:14 AM

Whoa, cool. Those little size boxes in the upper left will let you blow it up even more.

Are you in a non-urban area? The photos of my area are dated April of 2002.

Maybe there's some sort of rolling updates that take place.
